Association study of copy number variation in BMP8A gene with the risk of ankylosing spondylitis in Iranian population.

Background: Copy number variation (CNV) of DNA segments has been considered as an important component of genetic variation, affecting the quality and quantity of gene expression. Bone morphogenic protein 8A (BMP8A) has been reported to function in bone formation. With respect to the bone and joint complications in ankylosing spondylitis (AS), this investigation aimed to study the role of BMP8A gene CNV in impressing the gene expression as well as the disease risk.

A systematic review and meta-analysis of seroprevalence of varicella zoster virus: A nationwide population-based study.

Varicella zoster virus (VZV) causes chicken pox as a primary infection following which it becomes latent in neurons. It may then reactivate to cause shingles (herpes zoster). Severity of lesions and VZV pathogenicity are depended on the host's immune response and variant in VZV Dr Athina Myrto ChioniIdentification of VZV seroprevalance rate in general population may lead to develop new health strategic managements such as vaccination.

Allergic Rhinitis in Adults with Chronic Suppurative Otitis Media.

Introduction: Chronic suppurative otitis media (CSOM) is considered one of the most common causes of acquired hearing impairment in developing countries. CSOM is a multifactorial persistent inflammatory disease of the middle ear. A distinct pathophysiologic mechanism linking allergic rhinitis (AR) and CSOM remains to evolve.

Association between allergic rhinitis and migraine.

Background: Migraine and allergic rhinitis (AR) are two common causes of headache and facial pain that inflammatory mediators with vasoactive function play important roles in both of them. The aim of this research was to determine the prevalence of migraine in AR patients.

Materials And Methods: In a cross-sectional comparative study performed from June to December 2010 in patients with AR sign and symptoms referred to ear, nose, throat (ENT) clinic of a university hospital in Iran-Rasht, 46 patients with positive skin prick test were compared with 60 subject without AR signs and symptoms and with negative skin test.

Frequency of hepatitis B virus DNA in anti-HBc positive, HBsAg negative blood donors in Rasht, northern Iran.

Background: One of the important factors in the ensuing safety of blood transfusion is to use a sensitive screening assay for detection of blood-born infective agents such as HBV which transmits through transfusion. To improve the detection rate of HBV infection in blood donors, a cross-sectional study was conducted in Rasht, which is the largest city in the north of Iran to explore the possibility of using anti-HBc as a screening test.

Study Design And Methods: A total of 2041 blood samples negative for HBsAg, Anti-HCV, Anti-HIV I, II and RPR were tested to detect anti-HBc and then the positive anti-HBc samples were further checked for the presence of HBV DNA.
